TRM – 450® system
Garware TRM-450 of monofilament that consists of a dense web of crimped, interlocking, multi-lobed polypropylene fibers positioned between two biaxially oriented nets and mechanically bound together by parallel stitching with polypropylene thread. The TRM is designed to accelerate seedling emergence, exhibit high resiliency, and possess strength and elongation properties to limit stretching in a saturated condition. Every component of TRM–450 is stabilized against chemical and ultraviolet degradation which are normally found in a natural soil environment. TRM-450 contains no biodegradable components.
